I recently bought an "Intenso 6002510 320GB 2.5 inch External Hard Disk Drive" from Amazon (after reading good reviews) and I've had trouble running it on my 2011 Macbook Pro (Lion). Hopefully someone can help. I've read through numerous forum posts on devices not being recognised, but nothing that's helped so far. The drive displayed as normal for the first few days that I had it, but recently it's stopped recognising on both the desktop and on disk utility. I've tried the drive on another PC laptop and it shows up fine. The power/use light also comes on when plugged into both laptops, so there looks to be nothing wrong with the actual drive. Does anyone know of any reason why this is happening? Any help would be really, really appreciated.
